The player controls a particle of light on a mission from the outer reaches of the solar system to the sun.
Stretching and shrinking its path is necessary to collect photons, avoid dark matter, and go through light gates, which increase the point multiplier and score.
The photon path also becomes trickier, forcing the player to change their wavelength mid-arc to collect them and avoid damage.
Darkstation gave Waveform 9/10 stating "It is elegant in its simplicity, but don't let that fool you... there's a surprisingly large amount of game and replayability to be had.
[2] Destructoid also praised Waveform however said "Wave manipulation is a neat concept -- one I don't recall encountering in this form before -- but despite admirable attempts to introduce slight tweaks to the formula, it is eventually stretched to its limit"[9]
